Each zone is further divided into “a” and “b” subzones, indicating a 5-degree Fahrenheit difference.
In summary, here’s how the zoning works:
- Zone 1: -60°F to -50°F
- Zone 2: -50°F to -40°F
- Zone 3: -40°F to -30°F
- Zone 4: -30°F to -20°F
- Zone 5: -20°F to -10°F
- Zone 6: -10°F to 0°F
- Zone 7: 0°F to 10°F
- Zone 8: 10°F to 20°F
- Zone 9: 20°F to 30°F
- Zone 10: 30°F to 40°F
- Zone 11: 40°F to 50°F
- Zone 12: 50°F to 60°F
- Zone 13: 60°F to 70°F
Based on this classification, we can identify Atlanta’s designated zones.
